V4L/DVB (4115): Saa7134 card (LifeView3000 NTSC)

Add detection for the LifeView3000 NTSC model (right now the PAL version is
the only one in there, which is sort of annoying for me living in the US
and all..  sigh...)
This is one of those things that I like to classify "as a works for me so
take it or leave it" :-) .  Not that worried because its an $18 video
capture card that didn't look it was selling to well in the US, but then
again who knows.
The documentation needs updating too I bet but its behind anyways usually
to what is in the code.
